Schumann was born in 1893 in
Spandau. His father had a long criminal record and suffered from alcoholism and his grandfather had been convicted of pedophilia. He bought his first gun at a young age, practising by shooting at the local wildlife. When he was sixteen, he killed his female cousin, claiming that the gun accidentally went off while he was playing with it, spending some time at a correctional institution as a result. After completing his locksmith apprenticeship he was conscripted into the German army. He fought during the
First World War, where he was awarded the
Iron Cross 2nd class for his excellent marksmanship. Following the end of the war, he struggled to adjust to civilian life, embarking on his criminal career. Over the course of three years Schumann committed 7 murders, 15 attempted murders, 5 arsons, 11 rapes and a series of thefts and robberies. On 18 August 1919 Schumann shot 52-year-old forester Wilhelm Nielbock from
Spandau, which became his undoing. On 20 August 1919, he was arrested in
Berlin. The trial against Schumann started on 5 July 1920 in Berlin. == Trial and execution ==
